Specification of Letters Patent. l Ptente July 25, 1916.

Application filed February'21, 1914. Serial No. 820,166.

To all whom t may concern:

Be it known that I, FRANK H. HoBERG, a citizen of the United States,residing at Green Bay, county of Brown, and State of "Wisconsin, haveinvented new and useful Improvements in finding-Rollers, of which thefollowing is a specification.

My invention relates to improvements in winding rollers for the cores ofrolled paper packages.

The object of my invention is to provide means whereby a series of paperpackage cores may be mounted upon a single elongated roller and securelybound thereon for rotation with, ythe Aroller during a paper windingoperation, the cores being subsequently released for free withdrawalfrom the winding roller in a longitudinal direction. f

In the drawings-'Figure l is 'a side vie partially in longitudinalsection of fragments of a winding roller embodying my invention, showinga series of paper cores thereon in position for the paper windingoperation. Fig. 2 is a cross Sectional view of the same, drawn on line:l2- zc of Fig. 1.

Like parts are identified by the same reference characters in bothviews.

My improved roller comprises ahollow cylinder A provided with a seriesof internal spider brackets B, in which one or more longitudinallyextending rods C are journaled, these rods being provided with conicalexpanders D at suitable'intervals. The cylinder wall A is apertured onopposite sides of each conical expander D and an interiorly projectingplug or boss E is secured in each one of these apertures. Each ofinterior surface of'a paste'board corejon the roller, thereby lockingsaidcore against in"` 'dependent rotation and causing the same to rotatewith the roller. v l

eoA

It win be Observed that the expander D is' provided with anabruptlytapered .portion d at its smaller end and a slightly taperedvportion d at its larger end,so that saidlex pander will tend to remaininApinholling posltipn whendrawn between the. heads of the pms F. A coiledspringH may be interposed between anyone of .the `bearing, brackets Band a cross pin l1. on the rod C,'

said spring tending to retract the rod after 1t has been pushedtoexpanded position.

It may, however, be held against retraction by a locking cam .I pivotedto the end or head of the roller. ,A

It it not necessary that locking .pins F and expanders D be employed forall of the paste board cores which'the Winding roller v is adapted toreceive. It will be suiiicient if the end cores are' thus locked to thewindingv roller, since the intermediate cores may be held by frictionalcontact end to end with the end cores. It will be understood that afterthe cores are slipped on to the Winding .roller with the pinsin-retracted position,

these plugs is provided with an interior.

socket ey in whicha headed pin F is seated. The pin F projects outwardlythrough a hole in the plug E and is adapted to be projected radiallybeyond the periphery of the cylinder. A spring G is coiled around thepin F within the'socket e, this spring tending to retract the pin fromits radially pro'- jec'ting position. These pins are located in pairs onopposite sides of the expander D, and when the larger portion of theexpander D is moved between the heads f of the pins, said pins areforced outwardly against the tension of the retracting pins G. A set ofthese ins F projects through the peripheral wall of the roller at properintervals, so that the pins of each such set will, when projectedradially, bear forcibly against the rod C will be pushed inwardly, or ifone rod is used near each end of the winding rollers, both of theseArods may be pushed inwardly to force the expanders between the heads ofthe pins and Inovethe pins outward radiallyto lock some of the cores atleast by direct pressure of these pins against them.

The' ends of the winding roller may be provided with suitable journals Jand one end portipn is `preferably squared as illustrated at K, so thatit is adapted to fit into a squared socket or opening in a driving gearwheel or pulley. After the paper has been wound upon'the cores to form aseries of roller packages, the winding roller may be withdrawn bodilyfrom'the winding machine and from the driving gear Wheel, and` all therolls of paper carried thereon to any suitable delivery point, whereuponthe rod C will be released by an appropriate adjustment of the cams I,the rods thusmoving outwardly, drawing the expanders awayy from theheads ofthe pins and the pins being thereupon retracted by theirindividual retracting springs G. The rolls of paper with their coreswill then slip loosely from the winding'roller.

I claim-- l l. A winding roller adapted to receive sets of paper packagecores, in end to end relation, comprising a tubular core receivingmember adapted to receive and support a plurality of cores in end to endadjustment, plural sets of blunt ended pins radially socketed thereinand adapted to be projected through its periphery, the pins of each setbeing adapted to engage one of said cores, and means for actuating saidpins into and out of frictional pressure contact with package coresthrough which said roller passes,`

2. A winding roller for sets of paper package cores, comprising acylindrical member, a plurality of sets of blunt ended coreengaging pinsradially socketed in said cylinder and adapted to be projected throughits periphery at different points along its surface, and means forprojecting said Vpins through the cylinder Wall into positions to engagea plurality of package cores through Which said roller passes, saidactuating means comprising a longitudinally movable rod within theroller, tapered.

pin actuating expanders on said rod, and retracting springs operativelyconnected with said pins.

3;'A-winding roller for'sets of--paper package corescomprisingacylindrical member provided with a series of apertures, socket memberseach having screw threaded engagement with the wall of one of saidapertures and projecting inwardly, pins each enlarged at its inner endand seated in the respective socket members with their r outer endsprojecting through the socket members to the exterior' of saidcylindrical ward radially in opposition to the pressure of said springs,said pins having'blunt outer ends adapted to frictionally engage cylindrical tapered cores mounted on said cylindrical member, substantiallyas described.

n testimony whereof I allix my signature in the presence of twowitnesses.
